JAMES EDWARD BROADBENT, OF STALYBRIDGE, ENGLAND, ASSIGNOR TO ROBERTBROADBENT dz SON, OF SAME PLACE.

MACHINERY OR APPARATUS FOR WINDIN G YARN.

SPECIFICATION forming part of Letters Patent No. 512,860, dated January16, 1894..

Application filed April 13, 1893.

To all whom it may concern:

Be it known that 1, JAMES EDWARD BROAD- BENT,a subject of the Queen ofGreat Britain and Ireland, residing at Stalybridge, in the county ofChester, England, have invented Improvements in Machinery or Apparatusfor Winding Yarn or Thread, of which the following is a specification.

This invention relates principally to machines for winding yarn onbobbins or tubes usually called quick-traverse winding frames, and theobject of the invention is to simplify the motion for actuating, thetraverse or slide bar and at the same time render it capable of beingdriven at a very high speed, and also capable of adjustment to vary thelength of the traverse.

In order that this invention may be clearly understood I have annexedhereto two sheets of drawings illustrative thereof and have marked thesame with letters of reference corresponding with those inthe followin gdescription.

Figure 1 is a face View and Fig.2 a plan of my improved traverse motion.Figs. 3, 4, 5, 6, 7 and 8 show detached parts and modificationshereinafter more particularly referred to- The invention consistsinconnecting the traverse or slide bar a by alink 11 (preferablyadjustable as to its length as'shown on the drawings) to a crank pin 0carried by a sliding block d to which motion is given by the followingmeans. The block d is mounted so as to be capableof sliding in or upon acrankarm 6 or its equivalent, fixed upona cross shaftf at one end of theframe, and on a level with the said traverse or slide bar a. The block01 is also provided with a bowl q running in a grooved cam or plate Itfixed to the frame and parallel with the orbit or plane of The groove ofthis cam h is so curved around the center of the shaft f above namedthat it regulates the speed of the throw or traverse of the slide bar a,so as to' compensate for the slow motion of the crank pin in passing thehorizontal centers and make a sharp return at either end of the traversethus effecting by a simple modification of the crank motion what isusually done by a lever and a heart or circular cam or other morecomplicated device.

The crank pin 0 by which the link I) is con- Serial n5. 4.70.238. (N0model.)

nected to the block d is or may be adjustable in a groove 01 in thelatter as'shown detached at Figs. 4 and'5 or otherwise so that althoughthe traverse of the bowl g in its groove is constant that of the crankpin 0 may be increased or decreased according to theleng'th of bobbinrequired. In some cases the block at slides upon its crank-arm e whichis in the form of a rod see Figs. 1, 2, 4 and 5 and it is prevented fromturning thereon by passing the crank pin (2 through a small block 0shown detached at Fig. 3 sliding in a radial groove in a secondcrank-arm e fixed on the aforesaid shaft f and coinciding with thedirection of the first lever 6. Or the crank-arm 6 may be made in theform of a slotted or grooved box either square (as shown on Figs. 6 and7) or cylindrical (as shown at Fig. 8). In these cases the secondcrank-arm c is dispensed with and in the latter case the blocks c areemployed in the slots to keep the block (1 from turning in its crank-arme.

I claim as my invention 1. The combination with a traverse or slidebarand a crank-arm, of a block movable on said arm, a crankpin adjustable011 said block, a'link connecting said pin with said bar, and astationary oblong cam curved around the center of the crank and engagingwith said block, substantially as set forth.

2. The combination with a traverse or slidebar and a crank-arm, ofa-block movable on said arm, a crank pin adjustable on said block, alink adjustable as to its length and connecting said pin with said bar,and a stationary oblong cam curved around the center of the crank andengaging with said block, substantially as set forth. I

3. The combination of a traverse or slidebar, a crank-arm, a blockmovable on said arm, a crank-pin adjustable on said block, a cam formedbya groove in a stationary plate, a bowl secured to said block andadapted to run in said groove, said cam being curved around the centerof the crank, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES ED WARD BROADBENT.
